  script_tag(name:"insight", value:"The following vulnerabilities exist:

  - CVE-2024-32039: FreeRDP allows to integer overflow and out-of-bounds write in
  clear_decompress_residual_data.

  Note: As a workaround, do not use `/gfx` options (e.g. deactivate with `/bpp:32` or `/rfx` as it
  is on by default).

  - CVE-2024-32040: FreeRDP that have connections to servers using the `NSC` codec allows to
  integer underflow in nsc_rle_decode.

  Note: As a workaround, do not use the NSC codec (e.g. use `-nsc`).

  - CVE-2024-32041: FreeRDP allows to out-of-bounds read in zgfx_decompress_segment.

  Note: As a workaround, deactivate `/gfx` (on by default, set `/bpp` or `/rfx` options instead.

  - CVE-2024-32458: FreeRDP allows to out-of-bounds read in planar_skip_plane_rle.

  Note: As a workaround, use `/gfx` or `/rfx` modes (on by default, require server side support).

  - CVE-2024-32459: FreeRDP allows to out-of-bounds read in ncrush_decompress.

  - CVE-2024-32460: FreeRDP allows to out-of-bounds read in interleaved_decompress.

  Note: As a workaround, use modern drawing paths (e.g. `/rfx` or `/gfx` options). The workaround
  requires server side support.");
